Its a 7 bolt. 7k on the rebuild wiesco pistons. Greddy front mount, BOV, 3 inch turbo back, big 16G on stock fuel. Had to rip out an old AFC wiring harness to get it to run.

When I drive I get no BOV car does not seem to even make boost. Just breaks up real bad around 4k I tryed to get a log but the oil pressure shot way up again and I had to shut it off. I put the stock ECU in and the oil pressure stayed above mid way. It only shoots up when I put the dsm link ECU in. I have a new sending unit though I am going to try when I pick it up.

Car sat for an unknown amount of time. I am guessing months.

Car has a 1G cas what looks to be a Green top. On the 7 bolt head.

Idles like its missfiring. Idles really rough. I changed the plugs, wires are new, changed the oil and filter, put in dsm link.

The problem sounds like a large boost leak or maybe you BOV is stuck open, check the air pressure line going to it.
 
BOV is fine. Sounds like its missfiring almost but plugs are in the right spot. MAF is fine too.
 
Ok fixed the 02 sensor. But I don't think its being read by the ecu. DSM Link will not connect now. The radio stopped working and will not turn on. The lights are also stuck on. I try to turn them off but they do not shut off. Someone also disabled the clutch at startup so there is no need to push it in to start the car.

And there is one hell of an alarm system wired into the car.

Leaning towards an electrical issue at this point.
